Compact and Portable Methane Gas Detector. Capable of Detecting Methane anywhere in an Easy and Accurate Way. Target gas: Methane (CH4). Detection speed: 0.1 seconds.
Handheld laser detector for fast and safe detection of methane leaks at a distance of up to 30 meters. The new Laser methane mini (LMm) is capable of remotely detecting methane and other gases containing methane (natural gas or similar). It can quickly detect gas leaks or accumulated gas fom a remote location by pointing a laser beam at the target. The new LMm has been dramatically improved from its previous model and can now be used in coal mines, has lower power consumption enabling longer continuous operating hours, and a wider operating temperature range.
Laser Methane is based on the utilization of a laser-absorption spectrophotometer of methane gas for gas measurement. The system detects natural gas leaks by emitting a laser at specific wavelengths and analyzing the light reflected back from the ground to determine how much was absorbed by the methane in the natural gas. The measured gas volume is expressed by the methane column density (ppm -m): methane density (ppm) multiplied by the thickness (m).
Accumulated gas clouds in commercial and industrial facilities are commonplace. The Laser Methane mini allows for remote detection, removing the need for ladders, scaffolding or aerial platforms.
